LockConfig was one 35-field record: the lock's behaviour, the grab policy, nine colours, a type scale and a spacing scale, flat. It is now the seven behavioural knobs plus four nested records -- GrabPolicy(kind, disable_vt, retry_ms, log_every, preempt_weaker_holder), LockPalette, LockTypography and LockSpacing -- each overridden as a unit. Breaking for every constructor that passed grab=/disable_vt=/ grab_retry_ms=/preempt_weaker_holder= or a colour, and for every read of config.<colour>; hence the minor bump. screen-locker, leetcode-guard and diet-guard follow in their own commits. The two fail-open guards in the recovery loop carry per-line suppressions: catching everything is the property they exist for, and the check stays live for the next careless except. That was the last finding, so the gate now says 10. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01HHCbkJWXHjtTUaqvnHRAqA

"""Design tokens for lock surfaces: palette, type scale and spacing scale.
|
|
|
|
Split from :mod:`gatelock._config` so that :class:`LockConfig` reads as the
|
|
handful of behavioural knobs it is, with the visual vocabulary held by three
|
|
records an app overrides as a unit -- a palette is swapped whole, never one
|
|
colour at a time.
|
|
|
|
All defaults come from the ``unified-design-system`` docs
|
|
(``~/src/utils/unified-design-system/tokens.md``) -- the same palette used by
|
|
every one of kuhy's apps, Flutter and web included.

bg: Background color for the lock surfaces.

fg: Primary (near-white) text color.

muted: Secondary/caption text color.

field_bg: Background for "raised" surfaces (entry/spinbox fields,

input wells) -- one step lighter than ``bg``.

accent: The shared brand accent (buttons, primary actions).

|
success: Positive/on-track status color.

warning: Caution/pending status color.

|
danger: Negative/error status color.

|
on_fill: Text/icon color for anything drawn on top of a filled
|
|
accent/success/warning/danger surface (e.g. a button's label) --
|
|
NOT ``fg``. All four fills sit in the same mid-light band, so

|
near-white text under-contrasts on every one of them; callers
|
|
must pick ``fg`` vs. ``on_fill`` based on the widget's own
|
|
background, never hardcode one for all buttons.
|
|
focus_ring: Color of the *focused* widget's highlight ring. Defaults to
|
|
``accent``, because Tk's own default is black -- invisible against
|
|
``bg``. Pass to ``highlightcolor``; note ``highlightbackground`` is
|
|
the *unfocused* ring, so setting that one inverts the affordance.
